Trying my hand at a "set-ish" cube based on the Adventures in the Forgotten Realms.
Each of the original signpost uncommons are included to inform players off the archetypes as they draft:
Dungeon Exploration
In , there's also a "flicker" sub-theme to take extra advantage of some powerful "enter the battlefield" effects.
Dungeon Completion
Evasive Damage
Roll of the Dice
Treasure
Death Triggers
Equipment
Pack Tactics
Life Gain
Simic Value
There Be Dragons
All of the AFR "Class" enchantments have been included (for obvious flavor reasons)!
In addition to the AFR dungeons, I've introduced into the cube the Initiative mechanic which adds the Undercity to the possible dungeons one might encounter during play.
Still trying to pull out the Choose a Background
stuff...
